No, the Golden Mean is not a sunny, untroubled nullity, but a deep awareness of possibilities, with one eye cocked toward Comedy and the other eye skewed toward Tragedy, and out of this feat of balanced observation emerges Humour, not as a foolish amusement or an escape from reality, but as a breadth of perception, and what Heracleitus called "an attunement of opposite tensions, like that of the bow and the lyre". A reconciliation of opposites, indeed.
